Recovery services report recovery rates of 75 percent and higher on tagged items. Evidently, most people who find laptops are honest, and by offering prepaid returns and a reward on the tag (which lists an 800 number), the service makes doing the right thing easy.
The services have you register each item on the Web, with identifying information; afterward they contact you to arrange return if an item is found. The price is nominal, usually around $5 to $10 per tag, with quantity discounts. Vendors that offer labeling and recovery services include ArmorTag, BoomerangIt (pictured), StuffBak, TrackItBack, YouGetItBack.com, and zReturn.
